I want to buy a Big Muff Pi but the amp I have is a 15watt solid state practice amp, (its actually a Behringer modelling amp). Would a Big Muff be alright through this? I've heard distortion/overdrive pedals sound crap through solid state and Ive also heard it's only Overdrive.

ss + distortion/OD = poo. I had that amp and it was pretty bad, I wouldn't exactly call it a modelling amp. If you do get it, dont expect it to do anything magical, probably wouldn't sound any better than the amps distortion. Just save your money and buy a decent amp. Look at Ashton Viper 112 or something.

Theres nothing wrong with running od/distortion/fuzz through solid state amps. It simply depends on the amp you run them through. Generally, digital amplifiers will not take as pedals nearly as well as your bog standard, ultra clean tube/valve or normal ss.

Overdrive pedals are never said to be excellent with solid state because the VAST majority of those buying overdrive pedals use them to "push" the tubes into overdrive.

If you want a Muff, go for it. I doubt you'll keep that little amp for long as well y'know, simply consider your pedal collection, current or growing when you change..

So how do I know if mine is digital or not? it's a GM108, it says modelling but like Mackcity said its not really.

Well it's not digital, where it says "analog modeling" on the amp is the give away . It's just doing EQ/Gain adjustments rather than actually model different amps/cabs. It's pretty crap no offence. overturned is right though, if you want it for a pedal collection, go for it. If you're trying to find a magic pedal to right the amps sound, I doubt theres a pedal in the world that will help. If you are thinking of sticking with the guitar, a new amp should be the first thing on your list.

a good bigger SS would be ok with it. I still wouldnt recomend a muff, cuz personally i dont like them. But it would really be a huge waste of money to put a decent distortion pedal in front of any 15w ss amp. Just save your money and get a better amp that dosent need pedals to mask it's tone.
